An apparatus for effecting hyperthermia in a narrow body cavity or duct including: a disposable first part (1) having an elongate distal section (5) intended to be inserted into the cavity or duct having a centrally located, heat-releasing element (22), which is either surrounded by an elongate housing (24) or is itself constituted by an elongate housing, and a flexible and/or elastic enclosure (23) surrounding the housing in a liquid-tight manner, further including a device for supplying energy to the heat-releasing element (22) and an axially operating first inlet (135) at the proximal part of the housing, an outlet (133) from the housing being arranged for the supply of heat-transmitting medium under pressure for expansion of the flexible enclosure (23) to accommodate and to exert a controlled pressure on surrounding walls of the cavity or duct, a second inlet (131) to the housing (24), and medium-actuating device (13, 19) for the expansion of the flexible enclosure (23) and for internal circulation of the medium through the housing (24); and a permanent non-disposable second part (51) having a drive (55, 75) for the device (13, 19) for expansion and for internal circulation, and a connection (43, 59; 41, 81) for releasably interconnecting the drive (55, 75) and the device means (13, 19) for expansion and internal circulation.

1. An apparatus for effecting hyperthermia in a body cavity or duct comprising:a disposable first part comprising an elongate distal section intended to be inserted into said cavity or duct comprising a centrally located, heat-releasing element, which is either surrounded by an elongate housing or is itself constituted by an elongate housing, and a flexible and/or elastic enclosure surrounding said housing in a liquid-tight manner, further including means for supplying energy to the heat-releasing element and an axially operating first inlet at the proximal part of the housing, an outlet from the housing being arranged for the supply of heat-transmitting medium under pressure for expansion of the flexible enclosure to accommodate and to exert a controller pressure on surrounding walls of said cavity or duct, a second inlet to the housing, and a medium-actuating means for said expansion of the flexible enclosure and for internal circulation of said medium in a closed circuit from said second inlet through the housing exiting via said outlet and flowing on an outside of said housing to return to said second inlet; and a permanent non-disposable second part comprising drive means for said means for expansion and for internal circulation, and connecting means for releasably inter-connecting said drive means and said means for expansion and internal circulation, said medium-actuating means comprising a first means for the expansion of the flexible enclosure, and a second means for the internal circulation of the medium through the housing, said first means being capable also of removing medium from the system to bring the enclosure into a collapsed condition.
